Abstract
The utility model relates to a self-dragging resisting slip, wherein the lower part of a separating tie-in is milled into a strip. An external ledge on the strip is hung on an inner ledge on the lower part of the tie-in. A hanging joint is connected with a shell. A cone is installed in the shell. A window of the shell is provided with a slip. The lower part of a thruster is installed in the cone. The thruster locks the lower part of the separating tie-in in order to ensure that the strip formed by milling the lower part of the separating tie-in will not contract inward. The upper part of a pulling rod is connected with the thruster. A boss is disposed on the lower part of the pulling rod. The outer diameter of the boss is more than the inner diameter of a sleeve. The axial force for sealing a lower sealing separator is fixed by the slip in order to produce after the separating tie-in separating from the hanging joint, and hoist a tube pole for dragging. The boss on the lower part of the pulling rod can pull the cone upward in order to guide the sealing separator to unseal and recycle the slip of the utility model. No additional tube pole is needed for separating and dragging, so the work process is decreased, the working time is shortened, the cost is saved and the economic benefit is promoted.
